\[ 5(3 x+8)(9+4) \] Select all of the true statements below. 9 and 4 are like terms. \( (3 x+8) \) is written as a sum of three terms. In \( 3 x, 3 \) is a coefficient. In \( (3 x+8), 3 x \) is a constant. \( 3 x \) is a factor. None of these are true.

Step 1 ：\(9\) and \(4\) are not like terms.

Step 2 ：\((3x+8)\) is written as a sum of two terms, not three.

Step 3 ：In \(3x\), \(3\) is indeed a coefficient.

Step 4 ：In \((3x+8)\), \(3x\) is a term, not a constant.

Step 5 ：\(3x\) is a factor of the given expression.

Step 6 ：None of these are true.
